Mitutoyo 152-402 Micrometer Head, for XY-Stage, 0-25mm Range, 0.001mm Graduation, +/-0.002mm Accuracy, Plain Thimble, Spherical SR10 Face, For X-axis, With Vernier

The Mitutoyo 152 series micrometer head has a large-diameter thimble for fine positioning and ease of reading and either an anti-rotation device on the spindle or a spherical measuring face for use as an XY-stage feed. The vernier scale has graduations in metric units for taking precise measurements, and a white anodized aluminum rust- and glare-resistant finish. Models with an anti-rotation device have bidirectional graduations to 0.005mm, a hardened steel measuring face for durability, and a floating thimble mechanism for adjustable zero-setting to help provide accuracy. Models with a spherical measuring face are graduated to 0.001mm, have a carbide-tipped measuring face for wear resistance, and an adjustable spindle for zero-setting. The micrometer head has a plain stem for mounting in a fixture with a split-body clamp or setscrew. The measuring face is lapped to help provide accuracy.

Micrometers are precision measuring instruments that use a calibrated screw to measure small distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot. Micrometer heads are for mounting in fixtures, where they are typically used for measurement, or as stops or feeds.

Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
